Collect PremiumSIM invoices by customer number, prepaid or postpaid plan, SIM, service period, device charge, credit, and private-versus-business use under the German 1&1 mobile brand.
Do not treat every PremiumSIM payment confirmation as a tax invoice. PremiumSIM is a German 1&1 mobile brand with prepaid and postpaid products. A top-up receipt or app payment confirmation is not always the VAT invoice you need for bookkeeping. Keep prepaid top-ups distinct from contract invoices, and keep 1&1 Drillisch or sibling-brand documents from mixing when the legal issuer differs. Match the SIM or customer number to the person or cost center that uses the line.
Automatic download of PremiumSIM invoices
The planned flow joins portal documents with mailbox attachments in one review list. Until this provider connection is released, use the following checklist as the reliable manual path.
How it works
- Set the account and period. Note whether the PremiumSIM product is prepaid or postpaid before you store the month's documents.
- Check the original documents. Separate private SIMs from business lines and check the legal issuer when 1&1 sibling brands appear.
- Prepare the handoff. Keep payment or top-up confirmations only as reconciliation, not as a replacement for the tax invoice.

Frequently asked questions
How does BillGetter protect my PremiumSIM data?
BillGetter is being developed as a local and a cloud version. The permissions and data path of the PremiumSIM connection will be shown before you connect an account; the integration is currently on the roadmap.
Can I collect older PremiumSIM documents?
The available history depends on the later PremiumSIM connection and the documents retained in the account. BillGetter will document that scope before the integration is released.
Does BillGetter also collect invoices from email?
Mailbox collection is part of the planned BillGetter workflow. Email attachments and portal documents are intended to appear in the same review list, with the exact early-access scope confirmed before release.
Which PremiumSIM documents belong in the monthly set?
For PremiumSIM, start with: Postpaid mobile invoice, Prepaid top-up receipt, Credit or corrected invoice. Keep corrections and credits with the same period so the set remains complete and understandable.
Are PremiumSIM documents always saved as PDFs?
BillGetter is intended to retain the original format supplied by PremiumSIM; not every document type is necessarily a PDF. Before export, use this rule: Give bookkeeping the original PremiumSIM invoice or qualifying receipt plus the SIM or customer-number allocation.
